Collaboration between Businesses and Non-Profits

There are many examples of  collaborations between non-profit organizations and businesses.  At our February meeting, we discussed a case study about a social service organization trying to create collaboration with the business world to increase employment opportunities for disabled people (less-abled?)  We also watched 2 video clips with examples of collaboration between Businesses and Non-Profit organizations, specifically:  City Year and Timberland; and the Boston Museum of Science and Intel (computers).  We tried to apply the lessons from these 2 examples to the social service program, and brainstormed ideas to help the collaborative grow (they're actually trying to create a group that will meet monthly). 
Some of the Best Practices on this topic are: 

1. align the organizations around values - asking a business to donate $$ is (kind of ) trite, but getting them excited about the values of the non-profit provides excitement and can generate commitment, if they share those values.
2. consider that this is a 2-way street - it's wonderful if the business people actually get something from the non-profit, on top of satisfaction that they're helping with a social mission.  For example, the employees of Intel volunteered to mentor the students in the computer labs, and got a lot of satisfaction from that.  The employees of Timberland, who were scheduled to have a full-day staff retreat, decided to work together with the City Year fellows on a service day in the community.  In addition, the City Year fellows, who are trained in team building, presented team building activities to the Timberland staff.  A win-win all around.

We're interested in hearing about best practices and in examples from the real world of successful collaborations.
